REFRIGERATOR.

Application filed March 17,1923. Serial No. 625,796.

1 '0 all whom it may concern:

ators and the primary object of the inven tion isto provide an improved refrigerator having a novel means for cooling the interior thereof, which entirely eliminates the necessity of ice and thereby dispensing with the inconveniences and the cost contingentwith the use thereof.

A. further object of the inventionis to provide novel means located within the refrigerator for sucking in and cooling the air adjacent to the lower end of the refrigen ator and then circulating the cooled air through the body portion of the refriger ator.

A still further object of the invention is to provide an improved iceless refrigerator of the above character, which will be durable and efficient ,in use, one which will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

VVith'these and other objects in view the invention consists in the novel construction, arrangement and format-ion of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a perspective view of the improved refrigerator.

Figure 2 is a fragmentary central transverse section through the same.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally inclicates the improved refrigerator, which includes the body 5 supported upon suitable legs or the like 6. This body 5 includes top and bottom walls 6 and 7, the rear wall 8, and the side walls 9. The walls 6, 7, 8 and 9 are preferably provided with inner and outer spaced skins 10 and 11 forming a dead air space 12, which insulates the body portion of the refrigerator. If so desired this space 12 can be packed with suitable non-conducting material, such as cork, or the like.

m edium may be employed,

The front portion of the refrigerator is preferably closed by a pair of swinging doors 1?) and 14, which abut against a cen trally vertically disposed rail 15, when the same are in their closed position. Suitable removable food trays 16 can be provided for the interior of the refrigerator, so as to permitthe ready placing of articles of food therein. a

The lower wall 7 of the body portion 5 of the refrigerator supports a removable tray 17 which is preferably formed of sheet metal suitably treated to prevent rusting.

This tray 17 is adapted to receive some cooling medium such as water as indicated by the reference character 18, but it is to be understood that any other suitable cooling This tray. can have its forward end provided with suit-able handles 19 and can be removable from the front of the refrigerator if so desired.

Immersed in the cooling fluid 18 is a coil 20 of the desired diameter and this coil 20 has one end enlarged as at 21 and protruded exteriorly of one side wall 9 of the refrigerator. This enlarged portion 21 of the coil constitutes an inlet for the fresh air introduced into the refrigerator, while the opposite end of the coil is provided with an upturned end 22 which constitutes the outletfor the fresh air introduced into the refrigerator. This outlet for the coil 20 is disposed adjacent to the circulating paddle wheel 23 which includes a plurality of paddles or the like 24:. This wheel is secured to a shaft 25, which extends into the casing 26 of a spring motor of any preferred character. The shaft is the drive shaft of this spring motor. This spring motor can be wound up in any preferred manner such as by inserting a crank through a suitable opening in the rear wall 8, the space between the skins 10 and 11 receiving a sleeve or housing 27 for this purpose.

The upper end of the body 5 is provided with an outlet tube 28 provided with a suitable head 29, in order to permit the flow of air from the refrigerator.

In operation of the improved refrigerator, itcan be seen that the propeller wheel 23 will suck in air through the coil 20 from the exterior of the refrigerator and that this air will be cooled by the passage thereof through the coil, which is of course immersed in the cooling fluid. As the air is sucked out of the coil, the same is circulated upwardly by the paddle wheel and then out of the refrigerator through the tube and head 28 and 29.

It is to be also noted that the lower edgeof the paddle wheel can be placed in the cooling fluid and thus there will be a certain drip at all times from the propeller wheel which will cause the circulated air to become impregnated with the cooling fluid thus lowering the interior temperature of the refrigerator.

Changes in details may be made without departing from the spirit or the scope of this invention.

hat I claim as new is 1. An iceless refrigerator comprising a body including insulated Walls, a tray for the reception of a cooling fluid disposed in the lower end of the body, a coil immersed in said fluid having one end extending exteriorly of the casing constituting air inlets and its opposite end disposed above the cooling fluid and a propeller wheel for su-cl'cing air in through said pipe and circulating the air through the body.

2. A refrigerator comprising a body including insulated walls, a tray receiving a cooling fluid disposed in the lower end of the refrigerator, a coil immersed in said fluid having one end extended exteriorly of the body constituting an air inlet, the opposite being extended above the cooling fluid constituting an air outlet, a motor, a propeller wheel actuated by said motor for causing the sucking in of air through said pipe and the circulation of said air through the body.

3. A refrigerator comprising a body, a tray of cooling fluid disposed in the lower end of the body, an air cooling coil disposed in the tank one end of the coil being extended exteriorly of the body constituting an air inlet, the other end of the coil being extended above the cooling fluid and constituting an air outlet, an air outlet carried by the upper end of the body, a spring motor, and a propeller wheel operated by the spring motor having its lower edge disposed in said tank and adapted to suck air in through said coil and to circulate the air through said body.

In testimony whereof I aflix my signa ture in presence of two witnesses.
